I don't have an example of the resolution prior to today but the images were at a much higher resolution before. My department directly accesses the service in ArcMap. We also have a map within our real property system provided by Thompson Reuters that was created using geoanalyst. The images are blurry in that application as well.
Hi Lynne,
Please take a look at this document which describes how you can provide feedback to the teams:
How To: Provide feedback on basemaps and geocoding in www.ArcGIS.com
Hope this helps,
